Routine traffic stop ends in "largest fentanyl seizure in Michigan"

A traffic stop in Michigan led to the seizure of four kilograms of fentanyl, a potentially deadly synthetic opioid. 

According to law enforcement, this is the largest seizure of fentanyl in the state's history.

Troopers on I-94 near Paw Paw Township pulled over a driver for a routine traffic stop, citing traffic violations including improper lane use and a cracked windshield, the Michigan State Police said in a news release. Troopers detected "several indicators of criminal activity" when they spoke with the driver. After receiving verbal consent to search the vehicle, the troopers found four kilograms, or about 8.8 pounds, of fentanyl in a duffel bag.
